It's been a while so I thought I should provide an update for the Lampi tube roller lunatics club.
You may recall my last substantial post was on the topic of selecting the best match for my system in the 6SN7 spot. That award went to the red base RCAs, hands down.
Today has been spent rolling the back row on the Lampi Baltic 3. My dealer, Greg, kindly supplied three pairs to try, as shown in the photo.
First up were the RCA tubes. They offered a nice uplift in quality over the Telefunken ECC82-TK (12AU7) which I bought from SX Pro as a replacement for the factory supplied tubes. Mainly an improvement in clarity, like a veil has been lifted from the music.
Next came the Mullards, which come exquisitely packaged in their original boxes. They seem to drive my power amp better than the RCA tubes, and I think there is a tiny bit more detail and timbre from them. A more three dimensional rendition of the music.
The final set are the Mullards in the white boxes. They glow intensely when I turn the unit on, then they settle down. Whilst It's getting hard to tell the Mullards apart, I think I like these best. They have real presence compared to the others and more pronounced bass. Perhaps that's an artefact of detail? Who knows?
My only concern is that this last pair are marked "Mike" on the boxes. I hope he doesn't want them back ;-) You can see them installed on my B3 in my second picture and I think they might be impossible to remove!
In any event, this was all made possible by Greg Drygala who kindly loaned three sets for the back row and three sets for the 6SN7 position. I have now settled on the best of each and the DAC sounds glorious. A massive uplift from the factory supplied tubes. If you read this and own a B3, you owe it to yourself to get rollin'
